Re: [re2c-devel] re2c build errors

[Ulya <skv...@gm...>]

Hi Brad,


From what I can tell the error comes from the STL <map> header, not
from re2c code. The error is:

  'std::__1::map::__base' (aka 'int') is not a class, namespace,
  or enumeration

The fact that the compiler thinks that 'std::__1::map::__base' is 'int'
means that it cannot see its real definition ('std::__1::map::__base'
cannot be defined as 'int', as it is later used in expression
'__base::const_iterator', so 'int' here is just the default type assumed
by compiler when it cannot find any other definition).

Why it can't find the definition, I do not know. Maybe it failed to
find the necessary headers. Then also there are some redeclaration
errors, which also point at a mess with STL headers.

Note that we build re2c continuously for macOS on Github CI, here is
the latest build: https://github.com/skvadrik/re2c/runs/1382613288

Can you check the following things:

- Can you build a simple program that uses STL maps?
- Can you build it passing -std=c++98 to the compiler? (re2c uses C++98)
- What is your toolchain? (C++ compiler, version)
- What re2c version are you building?
- How exactly are you building it?
